Conglomerate grain size.
For example vfL sand ranges in size from 62 to 88 microns. Note that 1000 microns equals 1 millimeter. Thus, Cu sands range is size from 710 microns up to 1000 microns (or 1 m). The third listing is the Wentworth phi scale, a logarithmic scale used mainly in the early studies on grain-size statistics in the 1950's and 1960's.

Aeolian, sometimes spelled eolian or œolian, are deposits of windblown sediments. Since wind has a much lower carrying capacity than water, aeolian deposits typically consist of clast sizes from fine dust to sand [ 52 ]. Fine silt and clay can cross very long distances, even entire oceans suspended in the air.
